How to Measure the Expansion of Materials Due to Water Uptake

NETZSCH_wood_humidity

In the previous articles, focusing on thermal analysis under humidity, we have seen that thermogravimetric analysis and dynamic mechanical analysis help determine the influence of water on a material or substance. Thermomechanical analysis complements the analysis under humidity.

How to Detect Harmful Substances in Sporting Goods and Toys

NETZSCH Sporting Goods Toys

Sporting goods and toys for kids or pets are often made of flexible plastics. Some examples are sensory chewing toys, action figurines as well as balls of various kinds. A common polymer used for these applications is PVC (polyvinylchloride), because it can be made softer and more flexible by adding plasticizers. Therefore, they can evaporate or be rinsed out by saliva or sweat. Learn how to determine detect and identify plasticizers!

How Water Influences the Mechanical Properties of Polymers

Why is water a problem for a part made of thermoplastics? Textbooks describe that the water uptake for some types of polyamide (PA) is really high in both 50% relative humidity and in water. This alone would not be the problem, but the uptake of water leads to very different properties of materials. How can dynamic mechanical analysis (DMA) help with this issue?
